Abstract:

Abstract:The soot blower is an important device for ensuring stable operation of boiler, improving the thermal efficiency of the boiler, saving the energy and reducing the atmospheric pollutant emission. The performance and the applicable place of the soot blower were introduced. The formation mechanisms of the ash, the slag and the coke on the surface of the heat exchangers of different zones in the boiler and the structure features were analyzed. The boiler soot blowers were sorted, and their advantages and disadvantages were compared. The conclusion is that the frequency adjustable power sound wave soot blower has obvious functions to remove the ash, the slag and the coke.
